Abstract
Fremgangsmåte og anordning for beskyttelse av borehull-utstyr mot overdrevne trykk, hvorved det anvendes deler av volumkompenserende materiale som vil tåle de normale trykk som opptrer i brønnkanalen (10). I en versjon omfatter oppfinnelsen et antall halvseksjoner (26) av volumkompenserende materiale som er anbragt rundt en av rørdelene (22) i hulrommet (20) som inneholder fluider som kan øke i trykk til -et punkt nær grensen for beskadigelse av ringkanalens inner- eller ytterdel. En annen versjon omfatter en elastisk pakning (54) med en forsenk- ning (66) som opptar en ring (64) av volumkompenserende materiale som, under påvirkning av overtrykkstilstander, vil gi rom for tilstrømmende fluider.Method and apparatus for protecting borehole equipment from excessive pressure, using portions of volume compensating material which will withstand the normal pressures occurring in the well channel (10). In one version, the invention comprises a plurality of half-sections (26) of volume compensating material disposed around one of the pipe portions (22) in the cavity (20) containing fluids which may increase in pressure to a point near the limit of damage to the inner or outer channel. extremity. Another version comprises an elastic gasket (54) with a recess (66) which receives a ring (64) of volume compensating material which, under the influence of overpressure conditions, will allow for flowing fluids.
